Yeah, I think so, better find a reliable way to make a profit rather than gambling it on a solo mine coins..
But the upside is higher if you mine a new "spec mining" coins isn't? weather it solo or pool
I think solo mining is very risky. It is much safer to use the services of pools. This increases the profitability of mining.
its better to find a not very big mining pool or create it with an equal in volume partner - this will be much more efficient than a solo
